(1) Data based on characterisation results for LQFP80 device with VREF+/VREF-, not tested

in production.

(2) ADC accuracy vs. negative injection current: Injecting negative current on any of the

analog input pins should be avoided as this significantly reduces the accuracy of the

conversion being performed on another analog input. It is recommended to add a Schottky

diode (pin to ground) to standard analog pins which may potentially inject negative current.

Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in the I/O

port pin characteristics section does not affect the ADC accuracy.
